1.0 an whomit may concern:

Be it known that I, J can ERIcssoN, of the city, county, ,and State ofNew York, have invented a new and useful Improvement in ExplosiveProjectiles, of which the following is a specification, reference beinghad to the ac companying drawings. I

This improvement relates to that class of explosive projectiles known assubmarine tor- I0 pcdoes to be projected irom guns placed under water orbelow the waterdines ot the vessels which carry them.

It consists-in a novel construction of. apro jectile of this classhaving a wooden body and tail, whereby such body and tail are madecapable of resisting the tendency to crush them lengthwiseconsequentupon the force applied to project the projectile from a gun.

Figure 1 in the drawings is a central longi- 2o tudinal section of atorpedo constructed accord ing to myinvention. Fig.2is a rear end Viewof the same. Fig. 3 is a transverse section of the same on a largerscale in the line :0 a: of

Fig. 1.

The form of the projectile represented is cylindrical at and near itscenter of displace ment and conical in front and rear thereof, theconical profile ot' the front part or head, B, presenting a greater, andthe conical profile of the rear part or tail, 0, a lesser, angle to theaxis, thereby providing for a capacious powderehainber in the head forthe exploding charge, and producing an elongated tail. ()n the tail arefour radial and longitudinal steadying 5 wings orfins, 1 F. Theccntcrol' displacement is intended to be forward of the middle of itslength, and the weight of the projectile when charged; and ready for useshould be nearly equal to, but not greater than, the volume of o waterwhich it displaces.

The cylindrical portion A of the body is made of a solid piece of wood,with a ring or band,f, of iron firmly secured to its rear by screws i1'. The tail-piece U is also made of wood, and is solid except that itis bored cen trally for the receptionof an iron rod, which (No model.)Patented in England December 21, 1880. it

fits it tightlyand runs through i ts entirelength with a head at itsrear end. The front of the tail-piece has firmly secured to it by screwsj j a socket or flanged abutment-piece, receives therearportiontheringf-andis secured thereto by screws k k, as best shown in Fig. 3.The rod gabuts against the plate forming the front of the socket h, andit is secured in the wood by iron pins 1 l, inserted transverselythmnghthe wood of the tail-piece and'enteeiszg holes in-the red, as best shownin Fig. 1, E iminate I 31 are also represented 'of Wood halving theedgesfaced with plates of i ma or steel. "Thepowder chainber B'fits over thefrontof the wooden body .A lfld is secured thereto by screws 1' l.

The firingdevice orpercussioafuse S, which I is provided in the head ofthe projectile for firing the explodingciiarge, may be ot'any suitableconstruction; but I prefer to use a firing device such as is thesubject-matter of my application for patent filed June 18, 1881.

The within described construction of the wooden tail-piece with thecentral rod of iron and the connection of the tail-piece with the woodenbody by the iron abutment piece, against which the said central rodabuts, gives the wooden bodyand tail-piece all the strength and supportnecessary to enable them to resist the impact of the explosive force ofthe charge of powder employed to discharge the projectile from a gun.

'What I claim as my ii.lvention,and desire to secure by Letters Patent,is-- The combination, in a projectile having" a cylindrical body andconical tailpiece of wood, of an iron abutment-piece connecting the saidbody and tail-piece and a central rod of iron abuttin against saidabutment-piece and extending to the rear of the tail-piece,substantially as specified.
